constitutional protections foreigners don't. the 2001 legislation, and some legislation we've had since then basically said that even though if the government is targeting somebody who is a foreigner. and it's one end of a cfghts, they can pick up whatever the americans are saying at the other end. one thing that the fisa court authorized is in addition to what has been called the meta data. the telephone numbers you call or which you get called not the content. the government can pick up the content of american's e-mails, telephone calls, skype, whatever. within the foreign intelligence surveillance act as long as there's a foreigner someplace. that was another of the revelation of the snowden documents. but the fisa court has more to do with americans than you might think. >> host: since 2001, has the patriot act, the fisa surveillance, increased or decreased? >> guest: yeah.
